Permissible exposure limit

For beryllium, the PEL is 2 µg Be/m3 averaged over 8 hours.

Personal sample

An air sample taken in a worker's breathing zone (a hemisphere forward of the shoulders with a radius of approximately 6--9 inches) to evaluate a worker's exposure to airborne beryllium.

PPE

Personal protective equipment.

Regulated beryllium work area

An area, demarcated by the responsible employer, in which the airborne concentration of beryllium equals or exceeds, or can reasonably be expected to equal or exceed, the action level.

Removable contamination

Beryllium contamination that can be removed from surfaces by nondestructive means, such as casual contact, wiping, brushing, or washing.

Responsible employer

1. For DOE contractor employees, the DOE contractor office that is directly responsible for the safety and health of DOE contractor employees while performing a beryllium activity or other activity at a DOE facility.

2. For DOE employees, the DOE office that is directly responsible for the safety and health of DOE Federal employees while performing a beryllium activity or other activity at a DOE facility.
